Sweet principles of leaves of SYMPLOCOS SPP., Symplocaceae, were investigated. From leaves of S. MICROCALYX, trilobatin, 4'-0-|3-glucoside of phloretin (2', 4, 4', 6'-tetrahydroxydihydrochalcone), was isolated in a yield of 0.6 %. From leaves of both S. LANCIFOLIA and S. SPICATA, phlorizin,... mehr

Proteins consist of structural units such as globular domains, secondary structures, and modules. Modules were originally defined by partitioning a globular domain into compact regions, each of which is a contiguous polypeptide segment having a compact conformation. Since modules show close... mehr

Titanium alloy tibial segmented defect repair devices whose stems were coated with two layers of titanium alloy beads (Ti-6A1-4V, bead diameter c. 750 μm) were implanted in six beagle dogs. In four of the animals stems had been plasma-sprayed with hydroxyapatite (HA); the other two animals... mehr

Multiple shoots were induced from the apical domes of shoot tips of CNIDIUM OFFICINALE Makino (Apiaceae) by culturing them on Murashige and Skoog (MS) 1 static media solidified with 0.2% gelrite and supplemented with 6-benzylaminopurine (BAP) 10 -6M. An average of 5.3 shoots per segment were... mehr

Abstract Males of some internally fertilizing fishes devote reproductive efforts not only to mating activities but also to sperm production. Male reproductive efforts of the viviparous scorpionfish,Sebastiscus marmoratus, an ambush predator usually remaining on the substrate, were studied at a... mehr

Abstract Timing and sites of parturition of the viviparous scorpionfish Sebastiscus marmoratus were investigated both in aquaria and natural habitats of a rocky coast in southern Japan. Females released 4 mm TL larvae during the early night in winter. Night spawning may be advantageous in... mehr
